WU collaborated with fisher communities and related stakeholders restoring crab population in the Gulf of Thailand
Marine fish and shellfish are important sources of protein and income, through fisheries, for the number of people in Thailand, particularly those who live along the coastlines. It is recognized that, nowadays, marine fishery resources, especially the Blue swimming crab (BSC), have become depleted due to high fishing pressure. The BSC is one of the most economic species of fishery industries in Thailand and is exported worldwide, with Thailand being the fifth largest exporter. Hence, the reduction in the abundance of this shellfish inevitably affects the fishers and all the supply-chain sectors, which eventually affects the country’s GDP from fishery products.
Walailak University (WU) is located in Nakhon Si Thammarat, and the academic service area corresponds the Southern Thailand, where the marine fishery is among the main occupation of the local people. From the needs assessment surveys and requests from the stakeholders in BSC fishery, in particular the fishers per se, Thai Frozen Foods Association, local crab-processing factories, Thai Food Processor Association, Department of Fisheries (DoF), and NGOs such as the Federation of Thai fisher folk association and Thai sea watch association.
In 2018-2022, WU launched an academic project to improve BSC stock and fishery in the two main fishing grounds in Nakhon Si Thammarat and Surat Thani Provinces. The additional benefit of such a project is an opportunity to get certification on fishery improvement standards, i.e., Fishery Improvement Projects (FIPs), which is an advantage to preventing international trade wall and extending global markets for BSC products of Thailand.
The project launched by WU is called “Crab Bank,” a community engagement project to answer social needs, build partnerships and strengthen stakeholder participation. Various organizations financially support this project, particularly the National Research Council of Thailand, the Agricultural Research Development Agency, and the Ministry of Science and Technology. The “Crab Bank” program takes the caught gravid females BSC in the rearing condition, allowing them to spawn and then releasing the zoea and young crabs back to the sea. Along with the “Crab Bank” project, several scientific studies to assess the condition of the BSC stocks to evaluate the fishing habitat and other relevant issues have also been conducted, which collaborate with the listed stakeholders and other academic institutes, i.e., other universities in Thailand, NFI crab council (USA), World Wildlife Fund and Marine Resources Assessment Group (MRAG). The scientific is now focusing on Bandon Bay, the biggest BSC fishing ground in the Gulf of Thailand.
Training and knowledge sharing are essential processes for exchanging information among stakeholders. The research findings related to crab restoration were discussed with stakeholders in several meetings at the fishery community and DoF offices (Figure 1). In addition, academic information about the “Crab bank” operation was distributed to fishers keen to volunteer for the project. The evaluation of the fisher’s understanding of crab bank was also examined.

In 2021, in cooperation with local fishermen, a total of 84 “Crab banks” were already constructed along coastal areas in Nakhon Si Thammarat and Surat Thani provinces (Figure 2). At each bank, more than ten fishers are involved. They act as both a committee and a donor of gravid female crabs, which means that there are at least 600 fisher volunteers in these areas, which significantly increased compared to before the project’s launching.
As a result of undertaking a project to preserve blue crab resources for sustainable use under the “Crab Bank” project in 2021 (2564 B.E.), WU’s implementation, in collaboration with local fishermen and stakeholders, won the best Crab Bank learning center, being a model of working with the community to maintain the fishery ecosystem, provided by the National Research Council of Thailand (NRCT).

The societal impact related to sustainable development goals (SDG) of this project covered at least 5 topics which are life below water, decent work and economic growth, zero hunger, no poverty and partnerships for the goals. The short explanation of each topic is showed in following paragraph
